Definitions

  • the present invention relates to a hammer tacker comprising a body and a magazine which in its rear portion is connected pivotably via a connecting pin to said body in such a way that said magazine can in its forward portion be moved into and out of the body.
  • the disadvantage of providing the stamped holes with bushings is that from the manufacturing point of view it is very difficult to connect the bushings to the body in such a way that in their mutual relationship the bushings each have their central longitudinal axis coinciding with the centreline of the connecting pin, even if the stamped holes are so positioned, which makes it difficult to fit the connecting pin. There is also great risk that even if the bushings coincide with said centreline, they may each have a positioning which is skewed relative to the centreline, thereby likewise making it difficult to fit the connecting pin.
  • the present invention describes a hammer tacker with a structure which overcomes the problems indicated of a hammer tacker of the kind indicated in the introduction and is characterised by the body having integral bushings which have connecting surfaces whose longitudinal extent is greater than the thickness of the body material.
  • the present invention is also characterised in that the bushings are peened up from the body material.
  • the present invention is further characterised in that the bushings have an axial length which is between 1 and 2.5 times greater than the thickness of the body material.
  • the present invention is yet further characterised in that the bushings have an axial length which is between 1.5 and 2.5 times greater than the thickness of the body material.
  • the present invention is still further characterised in that the bushings have an axial length which is between 2 and 2.5 times greater than the thickness of the body material.
  • the present invention is characterised in that the bushings are each reinforced by a respective reinforcing sleeve which closely surrounds the respective bushing.
  • FIG. 1 is a general view of a hammer tacker according to the present invention
  • FIG. 2 is a schematic depiction of the parts essential to the invention of the stapler depicted in FIG. 1 ;
  • FIG. 3 depicts the body which forms part of the hammer tacker
  • FIG. 4 is a view along the section A-A in FIG. 3 ;
  • FIG. 5 is a side view of the depiction in FIG. 4 ;
  • FIG. 6 is a view corresponding to FIG. 5 in which a reinforcing sleeve is clearly shown
  • FIG. 7 is a sectional view along the section B-B in FIG. 6 .
  • FIG. 1 depicts a hammer tacker 1 according to the present invention.
  • the hammer tacker comprises a body 2 and a magazine 3 .
  • the body 2 and the magazine 3 are connected at the rear portion by a connecting pin which is not depicted in FIG. 1 but is described below.
  • the connection is such that the magazine can at a forward portion be moved into and out of the body in the motion represented by the double arrow P.
  • a staple (not depicted in the drawing) is to be driven into a workpiece 4
  • the hammer tacker 1 is moved downwards at its front edge towards the workpiece in the direction N and the magazine 3 meets the workpiece 4 .
  • FIG. 2 depicts schematically simply the body 2 and the magazine 3 and their connection 5 which takes the form of a connecting pin 6 .
  • the magazine is journalled within the body and it is also obvious from the drawing that the magazine can move relative to the body in the direction represented by the double arrow P.
  • the magazine reaches a stop when its upper portion 7 meets the lower portion 8 of the body and the magazine's movement in the opposite direction is limited by blocking means not depicted in the drawing.
  • FIG. 3 depicts the body as seen from the side and FIG. 4 is an enlarged view of the region of the body to the right of the line A-A in FIG. 3 .
  • These drawings show the connecting pin 6 and the bushing 9 to which it is connected.
  • the bushings 9 and 10 are integral parts of the body material of the side walls and are peened up, in a manner known to one skilled in the art, from the body material, so as to project from exterior surfaces of the side walls, and to be continuous with the side wall's.
  • the thickness of the constituent material of the body is denoted by T and the length of the bushing in the axial direction is denoted by D and comprises the respective connecting surfaces 11 and 12 of the bushings.
  • D is significantly greater than T, which means that the pin 6 is more stably fastened to the body 2 than if it was only connected to punched holes which would then only have the length T.
  • Peening to a length 1-2.5 times greater than the material thickness T results in an advantageous embodiment, which becomes more advantageous if the above value is between 1.5 and 2.5, and the best situation has been found to be a value of between 2 and 2.5.
  • the fact that the bushings are peened up from the body material means that there is no risk of play between the bushings and the body, thereby substantially reducing the risk of the magazine becoming unstably connected to the body.
  • FIGS. 6 and 7 corresponding respectively to FIGS. 4 and 5 show the bushings 9 and 10 provided with separate reinforcing sleeves 13 and 14 which may be necessary in cases where the body material is unsuitable for peening or where such a large axial length D is required that the bushings would thereby become too thin-walled.
  • Each sleeve closely surrounds an exterior surface of a respective bushing.
